Abstract
The utility model discloses a distortion-resistant fire-resistant rat-proof cable. The distortion-resistant fire-resistant rat-proof cable comprises a plurality of sets of conductors; each set of conductor is wrapped with a mica tape, a winding layer and an insulating layer sequentially, such that an insulating wire core can be formed; a plurality of insulating wire cores are stranded with one another so as to form a cable core; the cable core is wrapped with a glass fiber tape; the glass fiber tape is wrapped with a cross-braided inner sheath; the inner sheath is wrapped with a nylon protective layer and an outer sheath sequentially; and a filling layer is arranged between the cable core and the glass fiber tape. According to the distortion-resistant fire-resistant rat-proof cable of the utility model which is of structural simplicity, the inner sheath is of a cross-braided structure; the cross-braided structure has strong extensibility, and therefore, the distortion-resistant ability of the cable can be effectively improved, and the cable can be protected from being bitten by rats, and the service life of the cable can be prolonged; the mica tapes are arranged at the exteriors of the conductors, and therefore, the fire-resistant characteristic of the cable can be effectively improved, and the cable can withstand flames with about 800 DEG C, and the use safety of the cable can be ensured.
Description
Technical field
The utility model relates to the electric wire field, is specially the fire-resistant rodent-resistant cable of a kind of warp resistance.
Background technology
Along with the fast development of power industry, urban construction, all trades and professions are more and more higher to the requirement of cable.The employing that traditional cable is more the poor structure of thermal insulation flame resistant not.Therefore; when breaking out of fire; the not flame resistant baking of this class cable; be difficult to isolated flame, so flame is easy to these protective layers of ablation, makes cable directly be subject to the calcination of flame; cause cable can not work because of short circuit; and common cable is easily bitten by mouse, and anti-twist scarce capacity is subjected to distortion to affect the useful life that also can shorten cable for a long time.
The utility model content
The purpose of this utility model is to provide the fire-resistant rodent-resistant cable of a kind of warp resistance, easily by mouse, bitten to solve traditional cable in prior art, anti-twist scarce capacity, fire resistance is not good, the problem that affected by distortion to cause with the flame calcination cable to shorten and be short-circuited useful life.
For achieving the above object, the technical solution adopted in the utility model is:
The fire-resistant rodent-resistant cable of a kind of warp resistance, include the array conductor, it is characterized in that: every group of conductor all is coated with mica tape, lapping layer and insulating barrier outward successively, and formation insulated wire cores, the stranded formation cable core of several insulated wire cores, described cable core is coated with glass fiber tape, and described glass fiber tape is coated with the inner sheath that interlacing forms, described inner sheath is coated with nylon overcoat and oversheath outward successively, is provided with packed layer between described cable core and glass fiber tape.
The fire-resistant rodent-resistant cable of described a kind of warp resistance is characterized in that: described conductor is zinc-plated soft copper conductor.
The fire-resistant rodent-resistant cable of described a kind of warp resistance is characterized in that: described oversheath adopts silicon rubber to make.
The beneficial effects of the utility model are:
The utility model is simple in structure, and inner sheath adopts the design of interlacing, and the interlacing structure has larger extending space, has effectively promoted the anti-twist ability of cable, has extended the useful life of cable; Adopt the nylon overcoat design preferably of hardness and surface flatness, prevented that effectively cable from suffering biting of mouse; Employing arranges the design of mica tape outside conductor, effectively promoted the fire-resistance property of cable, can stand for a long time the flame temperature of nearly 800 ℃, has ensured the use safety of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the fire-resistant rodent-resistant cable of a kind of warp resistance, include array conductor 1, every group of outer mica tape 2, lapping layer 3 and insulating barrier 4 of all being coated with successively of conductor 1, and form insulated wire cores, the stranded formation cable core of several insulated wire cores, cable core is coated with glass fiber tape 5, glass fiber tape 5 is coated with the inner sheath 6 that interlacing forms, and inner sheath 6 is outer is coated with nylon overcoat 7 and oversheath 8 successively, is provided with packed layer 9 between cable core and glass fiber tape 5.
Claims (3)
1. fire-resistant rodent-resistant cable of warp resistance, include the array conductor, it is characterized in that: every group of conductor all is coated with mica tape, lapping layer and insulating barrier outward successively, and formation insulated wire cores, the stranded formation cable core of several insulated wire cores, described cable core is coated with glass fiber tape, and described glass fiber tape is coated with the inner sheath that interlacing forms, described inner sheath is coated with nylon overcoat and oversheath outward successively, is provided with packed layer between described cable core and glass fiber tape.
